Place cookie sheet on the top rack of the oven. When baking two sheets at one time, place them on different racks at different angles to allow proper air circulation, switching racks half way through the cooking time.

Bake cookies on a light silver cookie sheet rather than a dark colored sheet to prevent cookies from burning as easily.

If the outer edges of the cookies are getting browned before the center is completely baked, reduce oven temperature by 15 to 25 degrees and increase your baking time slightly. Do not increase oven temperature because the edges would just brown faster and the center would still be under baked.

Allow cookie sheets to cool in between batches. If sheets are hot, the cookie dough will melt and become too thin at the edges.
